So I have this complete D15b7 with tranny. Was trying to sell it and have had some interest but it's been nearly two years. I took the engine out because I was putting in about 3-4 qts. every 5-7 days. No blue smoke coming out tailpipe however the oil was pouring out of the exhaust pipe and unto the back bumper, trunk and tail lights. So I figure either the piston rings or oil rings are gone and the motor needs rebuilding. One of my dreams has always been a turbo D, which has been spurred on by ScttyDB , and please no comments about b engines. I want something very mild so I thought maybe rebuild with oem parts. Probably will have to had the block bored slightly maybe .010 or .020 and also have the head ported. I would actually like to do everything myself, it's a project. and then piece together a HMT set-up really small. I have a CB7H22 right now but I miss my Civic. How difficult is it to rebuild a head and what type of cost am I looking, generally, for a shop to bore the block and level the deck as well as having head work. Please share.
